• Lead downstream process development studies, including chromatography screening, process optimization, and scale-up activities to support client programs from early development through commercialization
• Perform and oversee in-process and routine analytical testing to support downstream development activities, including protein concentration determination (A280), HPLC-based assays, and other relevant analytical methods
• Independently execute downstream unit operations using chromatography systems, filtration equipment, and associated process analytical tools with minimal supervision
• Support process scale-up, technology transfer, and manufacturing operations by developing robust buffer preparation strategies and downstream processing workflows suitable for pilot and GMP manufacturing environments
• Compile, analyze, interpret, and present experimental data; author technical reports, development summaries, protocols, and client-facing documentation; present findings during internal project reviews and client meetings
• Lead troubleshooting and continuous improvement initiatives to enhance process performance, robustness, productivity, and scalability
• Contribute to the evaluation, implementation, and validation of emerging technologies, process analytics, laboratory automation platforms, and process intensification strategies to improve development efficiency
• Apply experience with laboratory automation, process intensification, process analytical technologies (PAT), high-throughput process development, and data analytics (highly desirable)
• Mentor junior scientists and provide technical guidance across downstream process development activities
• Perform other duties and project-related responsibilities as assigned

Qualifications

• Bachelor's degree with 3–4 years of relevant biopharmaceutical industry experience, or a Master's degree in Chemical Engineering, Biochemical Engineering, Biotechnology, Biological Sciences, or a related field
